Stock trading limit order coupled link (lock)

ABSTRACT

This invention has the potential to generate very good return on investments from stocks that are conservative in movement. This invention will greatly benefit investors that do not have the time to constantly trade stock yet want to take advantage of normal price fluctuations. The Limit Order Coupled LinK (LOCK) invention, for example, will take a buy order, complete the transaction at the specified price, then automatically resubmits a new order to sell at a specified higher price. If specified, the process can automatically cycle through the buy-sell process a set number of time allowing the investor to take advantage of intra-day market moves and normal stock price fluctuations with no personal investor evolvement. The LOCK order, with set profit margins, allows on-line traders and brokers to place one order, which will automatically generate logical, sequenced additional orders returning a profit on each transaction. LOCK will benefit both the investor and the stock trading company.

BACKGROUND OF THE INVENTION

This invention applies to buying and selling stocks, options, commodities, bonds, and most forms of equities and securities. This invention has useful application for the individual investor, the securities broker and others who trade securities.

One of the strategies for buying and selling stock is to buy stock at one price forming a ‘long’ position then selling the stock at another price, closing out that position. Other strategies include forming a ‘short’ position by borrowing stocks then closing out the position by buying back the securities at another price.

On-line securities trading allow the common investor the ability to buy and sell stocks and securities over the Internet at minimal transaction costs. Numerous electronic trading companies have been established and tens of thousands of individual traders have made tens of millions of securities transactions every week. Many individual traders continue to dedicate hours to buying and selling securities in hopes of benefiting on minor stock price moves. Many must take time out of their regular busy day to watch the market and trade stock. This extra time required detracts from a person's regular job and also leads to less-than-optimal stock trading results.

The current Internet investment approach requires investors to access their accounts to submit a buy order, then re-access their accounts to receive a list of the daily transactions. If an investor submits a limit order, the stock price must reach the limit order price before the transaction takes place; often the order is not filled the same day. If the investor submits a market order, the transaction occurs quickly, but the investor must wait to find out the cost of the transaction that was determined by the market.

In either case, the investor must submit an order, wait for the transaction to occur then develop and submit a second order to close out the position in hopes of making a profit. This current state of the art process is time consuming and may require investors to check their accounts several times a day. The result is loss of time or interference with the investors' regular job, and in a fast-moving market, investors may miss the opportunity to close out their position.

To take advantage of market volatility, investors must continually monitor the market. First they need to decide when to buy, then, once the buy transaction has occurred, they must immediately submit a second order, usually a limit order, to take a sell position and close out the position at a predetermined price.

Of course investors can still use traditional stockbrokers to execute a buy-sell or sell-buy strategy. However using a broker adds to higher transaction cost and the broker must also watch the stock and execute two sequenced orders.

My invention will replace the current methods and processes, allowing investors to lower transaction costs. With my invention, investors can place one order that will buy the security at a preset price and sell the security at a gain price, without requiring additional investor actions.

SUMMARY

The Limit Order Coupled Link (LOCK) invention is designed to allow the online investor or stockbroker to enter one transaction order, which will execute an automatic sequenced transaction strategy for buying and selling a security for a predefined profit. This invention offers a number of advantages. It frees the on-line investor or stockbroker from the burden of monitoring a selected securities price movement. Instead, management software module in the electronic trading system will execute the buy-sell strategy. LOCK simplifies the current process in which investors must submit orders, one to establish an open position and a second to close out a position.

EXAMPLE Current Method

Two separate orders requiring a time delay to confirm 1st order was completed before submitting the 2nd order:

Order Stock Quantity Buy Price #1 Buy-XYZ 100 56

Once confirmed that transaction is completed then a new order is submitted.

#2 Sell-XYZ 100 57

LOCK Method:

1st order contains information for constructing the 2nd order. Therefore, execution of the first order automatically generates the second order. Investors only needs to submit one order:

Stock Quantity Buy Price Lock Price XYZ 100 56 1

The above LOCK order translates to “buy 100 shares of XYZ at $56 per share and once the transaction has occurred (open position), submit a sell order for 100 shares of XYZ at $57 per share.” Once the securities are sold the position is closed and the investor walks away with approximately $100.

LOCK offers big advantages, yet is very simple to implement, adding just one more data field. Currently, an electronic transition required at least five data fields: (1) buy or sell, (2) securities symbol, (3) quantity, (4) market price or limit price, and (5) the time the order is good for day-order or good-till-cancel. LOCK adds one more data field. This is the LOCK field that automatically locks a transaction in place at a price the investor determined. An example would be (1) buy (2) stock XYZ, (3) 100 shares, (4) at market price for a share, (5) good-till-cancel, (6) LOCK 1. This would be translated by the computer network as a buy order for 100 XYZ at market per share and place the order to (1) sell (2) stock XYZ, (3) 100 shares, (4) at purchased price plus $1.00 a share, (5) good-till-cancel. This will allow investors to place their orders and not have to watch the market to complete their strategy. Investors are free to conduct other business and, if the 100 shares of XYZ stock they procured goes up $1.00, the sell order will be executed and he will profit $100.00 minus the transaction costs.

LOCK actually takes some of the risk out of stock trading provides better chances that the investor realizes a profit. Under the current system, investors mentally set a sell price, but then when the stock passes that price often the investor moves the sell price out as well. Then, when the stock price falls, the investor looses profit opportunity until or unless the stock price goes up again. With LOCK, the investor can set disciplined, predefined gains on securities. The investor decides at what price to buy stock and what price to sell it. LOCK automatically buys and sells at the investor's predetermined prices. As a result, the investor need not constantly monitor fluctuating stock prices and is guaranteed a profit should the stock rise to the predetermined sell price.

Another significant advantage of LOCK is that small and part-time investors can realize a profit from smaller stock gains typically produced from daily market volatility. This provides an alternative to “buy and hold” strategies.

DESCRIPTION Main Embodiment

The stock and equities trading Limit Order Coupled Link (LOCK) method and invention centers on additional buy/sell profit information contained in the investor's equities order. It also encompasses the software, designed to convert this order into two or more orders that can open and close out the investors position with preset profit goals.

The LOCK method and invention comprises (A) an investor who invests in a securities market with an objective to make a profit; (B) a host securities broker (such as E-Trade, Ameritrade, etc.) with a computer network, for handling their transaction. The host computer network includes a database server that provides an electronic security order template. With this template in place, the host computer network can store and organize security transaction request so that when an investor initiates a transaction, the network processes the request and sends it to a security exchange (such as New York Stock Exchange, NASDAQ, etc.); (C) individual computer workstations for each investor or broker. Each computer workstation would include a video monitor, a means for the investor of broker to send user commands to the host computer network, and a means for the investor or broker to receive and display (on the video monitor) security order templates and instructions transmitted from the host computer network; (D) a communications network electronically linking the investor's computer workstation to the host computer network; (E) a two-part securities exchange order (referred to as the LOCK order) that the investor initiates and that contains specific instructions for the host computer network to transact the security exchange. The LOCK order would include instructions and information for buying or selling a security, the name of the security, the quantity of that security, to buy the limit price or current market price at which to transact the security exchange and the increase or decrease in security price to initiate part-two of the transaction (referred to as the LOCK profit); (F) a software module that allows the investor at the computer workstation to interact with the host computer network. With this software the investor can select security exchange options and transmit them to the host computer network then receive confirmation that was underway. (G) an additional software module (referred to as the LOCK management module) as part of the securities broker host computer network. This software would link the host computer network to the security exchange markets and track and monitor the status of the investor's LOCK order. At the appropriate market price, the software would initiate a two-part, sequenced securities exchange order to buy a stock at the investor's specified price, then add the specified desired profit price and place a second order.

With LOCK the investor could enter as little as one extra data field when placing a stock order. This additional information would be the LOCK profit margin. By entering this number, the investor would tell the investment company or securities broker to execute a LOCK transaction (buy and sell linked limit order).

Currently the minimum information required for an electronic transition is buy or sell 2, securities symbol 5, quantity 6, market price or limit price 8, and the time the order is good for day order or good till canceled 4. A LOCK order adds one more data field. This field is the LOCK field of the change in security price such as 11/4 or 1.00 representing $1.25 or $1.00 change in stock price. An example would be: buy, 100 shares of stock XYZ, at market price for a share, “good to cancel”, LOCK 1. Good to cancel term referrers to the order as being placed until filled or canceled by the investor. This would be translated by the computer network as a buy order for 100 XYZ at market per share and then immediately place an order to sell 100 shares of XYZ stock at purchased price plus $1.00 a share, with an order that is “good to cancel”. This allows the investor to place an order and be free to conduct other business. If the 100 shares of XYZ stock the investor has procured goes up $1.00 LOCK would automatically execute the sell order ensuring a profit of $100 minus the transaction costs. LOCK allows investors to make predefined gains on securities place.

Operation Main Embodiment

The LOCK method and invention centers on additional buy/sell profit information contained in the investor's equities order. It also encompasses the software that converts an investor's order into two or more orders that open and close out the investor's position with preset profit goals.

FIG. 1 shows information typically required and found on electronic transaction equities order 1 today, including instructions from the investor to buy or sell 2, whether to form a long (buy) or short (sell short) position 3, the time the order is valid either for the remainder of the market day then canceled (also referred by investors as “fill or kill”) or the leave the order valid for multiple days until filled or canceled by the investor 4, the stock symbol 5, the quantity of stock 6, whether the order is a market order (to trade at the prevailing trading price) 7, or a Limit Order (to trade at a specific price or better) 8.

FIG. 2 is shows the addition of the LOCK information box 9, to the FIG. 1 example order form. If an investor wished to execute a LOCK trade, the investor would simply add the movement value of the equity 10 to close out the position. This simple addition of information LOCK value 10 is all that the investor would have to add to execute the LOCK process. If the investor enters an order to buy a stock and enters a 1.00 in the box this would be interpreted by the LOCK process (FIG. 3) and module (FIG. 5) to sell the equity at 1.00 more than the purchase price. Alternate embodiment of this number could be to have the investor specify the amount of profit desired such as $150.

FIG. 3 shows the logic execution and conversion of the LOCK invention and process. FIG. 3's right side represents the investor's input request that is used to execute Part one of the LOCK process. The buy/sell instruction 2 convert from part 1 from buy to part 2 to sell 11. An example is if the order states to buy 100 XYZ, part 1 will buy then convert to a sell order in part 2. The order's time to be valid box in part 1 can be specified as day or good to canceled 4. If part 1 on the LOCK order is executed, this information will convert to a good till canceled order. An option for the investor is to see the status of his order and request modification to the LOCK order or cancel the second half of the LOCK order if unexecuted. An example may be that the investor's LOCK order is executed and he now holds 100 shares of XYZ and is waiting for a LOCK price move of 2.00 before he sell. During this time the investor queries the electronic investment company on the status of the LOCK order and sees that part one has been executed and now wished to cancel the “sell” order in part 2 of the LOCK order. The investor submits a cancellation request and, if received in time, the LOCK order could be canceled and the investor would only have part 1 of the LOCK order's results. Similarly, if the investor wished to cancel the entire LOCK order before part 1 has been executed, the order would be cancelled in a method similar to canceling traditional unexecuted orders.

The stock symbol 5, and stock quantity 6, remains the same in part 1 and part 2. Alternate embodiment could change the quantity, such as selling half in part 2 then cycling through part 2 again selling the second half a an increased price. The price selection for part 1 involves either a market order 7, which executes the trade at the prevailing market rate or a Limit Order 8, which specifies a price. For the investor to execute a Limit Order normally he or she must check a box and enter the price at which to execute it or if market conditions permit, at a better price. The part 1 order executed price in combination with information in the LOCK box 9, and the LOCK price 10, will form the Limit Order execution price for the part 2 of the LOCK transaction.

FIG. 4 shows the conventional electronic trading process requiring two orders to open and close a position. The process begins with the investor 17 placing a buy or sell order 18 with an electronic trading company or organization 20. The electronic trading company 20 generates an electronic order 21 that is submitted 22 to a securities exchange 23. The order 21 is presented in the trading pit 24 and when a buyer/seller accepts the order, the order is filled 25. Once the order has been executed or filled 25, the electronic trading company is notified and the investor's account is documented 26 and the investor 17 is informed. The investor 17 must now place another order 27 to close out his or her position and make a profit. An example of this process would be if an investor 17 initiated the process to buy 100 shares of stock XYZ at $50.00 a share 18, received notification that the order was fully executed 26 now the investor 17 must resubmit an order 27 to sell 100 shares of XYZ at $52.00 to make a profit. The order 27 is submitted to the electronic trading company where a new order is generated 28, order submitted 29, presented in the trading pit 30, filled, 31 documented and the account is updated and the investor notified 32. Current state of-the-art methods require the investor or broker 17 to be involved in both transactions.

FIG. 5 shows the main embodiment of the LOCK method, process and order flow sequence for opening and closing a LOCK order. The method begins with the investor 17 submitting a LOCK order 19, which contains sufficient information as described in FIG. 3. The LOCK order 19 is submitted to the electronic trading company 20 where the order is identified as a LOCK order and enters the LOCK management module process 12. The LOCK management module 12 comprises the software interfaces that receive the LOCK order 19 document and generate a tracking record 33, record the LOCK increment 35, monitor the submission of the first part of the LOCK order submission 34, as the order 34 enters the securities exchange 23 trading pit 36, and the order is filled 37, then record the first order being filled 38, generate the second part of the LOCK order 39, and submit the second part of the LOCK order 40. The second part of the LOCK order 40 is resubmitted to the trading pit 41 and once the second order is filled 42, the electronic trading company 20, records the account balance 43 and notifies the investor 17 that the LOCK transaction has been completed.

The LOCK management module 12 will also provide the investor 17 with status when requested. For example, if the investor 17 wishes to check on the status of the LOCK order 19, he or she could electronically contact the electronic trading company 20 and receive an update on the LOCK order 19—for example, where the order was in the process, such as whether the first part of the LOCK 19 order was filled 37, second part of order submitted 40 and in whether it was the trading pit 41 waiting to be filled.

Description and Operation Alternative Embodiments

Alternative embodiments include inserting the option to automatically re-cycle through the process again and an additional option to increase or decrease the buy/sell prices. FIG. 6 and FIG. 7 shows alternative embodiment of the LOCK method by adding a number of cycles and increment options to the methodology. FIG. 6 shows the additional information required to cycle through the process. FIG. 7 shows the methodology for reentering the LOCK management module 12. The addition of “Number of Cycles” 44 would allow the investor to automatically reenter the LOCK process again in hopes of making more profit. An example of specifying two cycles would mean to buy 100 shares of XYZ (with a LOCK price of $1) at $50 a share, sell at $51 a share, buy back at $50 and sell again at $51. This investment process would allow the individual investor to take advantage of daily small stock fluctuations.

Another option would be to increase the price increment for each cycle 45. Investors would use this process to take advantage of a stock price that is moving up. An example is specifying buy 100 XYZ at $50.00 with a LOCK price of $1, number of cycles of 3 and an increment of $0.50. This would translate to buy 100 shares of XYZ at $50.00, sell at $51.00, buy back at $51.50, sell at $52.50, buy back at $52.00, and sell at $53.00.

Another embodiment would be to locate the LOCK management module 12 on the investor's own computer.

FIG. 8 is an alternative embodiment that would locate the LOCK management software module 12 on an investor's computer 46. This method and approach is similar to the primary methodology requiring LOCK information to automatically generating multiple sequenced orders and executing the number of cycles and increments selected by the investor discussed below.

The LOCK process could include an option allowing an investor to cancel a LOCK order anytime during the process. For example an investor could decide to hold on to a stock purchased in part 1 of the LOCK order then cancel the sell side (part 2) of the LOCK order. The stock symbol 5, and stock quantity 6, remains the same in part 1 and part 2. Alternate embodiment could change the quantity, such as selling half in part 2 then cycling through part 2 again, selling the second half at an increased price.

An alternative embodiment of the LOCK invention method is to use percents as the LOCK, rather than stock prices. For example an investor could enter a percent, such as 2%, rather than 1.5 points of stock price. Suppose the stock is trading for $40.00 a share. The investor could enter 1.5 meaning a move of $1.50 up would constitute a sell limit order or by using percents, the investor could enter 2%, meaning a move of $0.80 cents up would initiate a sell limit order.

Additional percent alternatives in defining the LOCK with respect to the trade price could be offered to the investor to discount the trade or commission costs. An example would be if a stock is selling for $100.00 a share and the investor wishes a 5% gain, and the cost of a limit order transaction is $10.00 then the trade in and out cost is $20.00 so the LOCK could be interpreted as trade at a 5% gain after charges and commission. The trade that completes the LOCK would be $107.00 a share based on 100 shares and a LOCK of 5% profit. Percentage LOCKs offer the investor a simpler conversion for setting investment goals.

CONCLUSION, RAMIFICATIONS, AND SCOPE

The LOCK invention and methodology will allow investors to define specific investment strategies and execute these strategies with minimal involvement. This invention will further allow investors to take advantage of small and repetitive stock price movement that, over time could translate to significant profits. The LOCK management module can reside at an online investment company or on investors' computers. This invention will significantly increase the volume of trades for online investment companies. This strategy moves away from traditional by-and-hold strategies to one of attempting to mass small but consistent gains. LOCK is especially advantageous to the average investor who does not have much time to watch the market's constant motion.
